l Appncation mea may 25, 191e.

To all whom it may concern:

Be it known that I, AL ANDREWS, a citizen of the United States, `residing at Moorcroft, in the county of Crook and State of wlyoming, have invented certain new and useful Improvements in lVater-Flevators; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to improvements in elevators such as those used for lifting the wa ter for irrigating purposes, the object being to provide a device of this class which may be easily and inexpensively manufactured and marketed yet which regardless of these advantages will be highly efficient and durable.

`With the foregoing general object in view, the invention resides in certain novel features of construction, and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure 1 is a side elevation of the invention showing one manner in which it may be a plied;

Fig. 2 is a top-plan view thereof;

Fig. 3 is an end elevation;

Fig. l is a central vertical longitudinal sectional view; and

Fig. 5 is a vertical transverse section taken on the plane of the line 5-5 of Fig. 4.

In specifically describing the structure shown in the drawings above briefly described, similar characters will be placed on corresponding parts throughout the several views and reference will be herein made to the numerous elements by their respective indices. To this end the numeral l designates a pipe preferably constructed of a single sheet of metal with its edges brought substantially together and bent laterally to provide parallel flanges 2 on the exterior of said pipe. The flanges 2 contact with opposite sides of an elongated board or plate 3 and are secured thereto by bolts or the like 4f. One-half of the board 3 extends throughout its length into the pipe l and constitutes a flange for a purpose to be described while the other half of said board is disposed on the exterior of the pipe and 'Specification of Letters Patent.

Serial No. 99,910.

serves as a track for guiding the water elevating members to be. hereinafter referred to.

Upper and lower sprocket wheels 5 and 6 are mounted at the upper and lower e'nds of pipe 1, the lower' sprocket being preferably carried between a pair of metal bars 7 whose inner ends are anchored by certain of the bolts Il. The upper sprocket 5, however, is keyed or otherwise secured on a transverse shaft Shaving any suitable means by which it may be driven, a pulley 9 being preferably secured on said shaft for this purpose. The shaft 8 is mounted in appropriate bearings 10 on the upper ends of brackets 1l which are secured to an end board 12, the latter having a circular opening through which the upper end of the pipe 1 passes, this end being preferably slit at intervals and bent laterally as indicated at 14 to provide attaching lugs which are secured by screws or other preferred means 15 to the upper surface of the board 12. The lower edge of the board 12 is provided with laterally extending journals 12"L for reception in bearings carried by the upper ends of posts or the like 16.

An endless belt or chain 17 is trained around the sprockets 5 and 6, the lower' reach thereof being disposed within the pipe 1 along the lower edge of the board 3 while the upper reach of said belt or chain extends along the upper edge of said board. A plurality of water elevating members in the form of disks 18 are secured at spaced points on the chain 17, said disks necessarily having radial slots 19 to permit them to pass around the sprocket wheels 5 and 6. These slots, however, are closed by the inner half of the board 3 as the disks 18 move upwardly within the pipe 1, thus insuring that no leakage of water shall take place. As disks 18 move downwardly, the slots 19 straddle the projecting upper edge of the board 3 and are thus effectively guided onto the lower sprocket 5. This arrangement also prevents vibration of the upper reach of the chain 17 and will overcome any possibility of said chain `jumping from the sprocket 6.

Completing the structure of the improved elevator is a shoe 20 secured to the lower end of pipe 1. This shoe is adapted to rest on the bed of a stream from which water is being drawn or upon the bottom of a receptacle in conjunction with which the machine may be employed. The upper edge of the Y shoe 20 is preferably curved or flared outwardly as indicated at 2l to prevent the edges of the disks 18 from catching thereon.

l nals 12a will permit the pipe 1 to incline the necessary amount to dispose the shoe 20 upon thebed of the stream as depicted clearly in Fig. 1. When now the pulley 9 is rotated to move the lower reach of chain 17 upwardly within pipe l, the disks 18 will carry water upwardly and at the same time they will create a partial vacuum within the pipe which will also assist in elevating the water.

From the foregoing it will be obvious that the object of the invention has been attained and that further description and exposition is therefore superuous. In conclusion, however, I will state that although certain specific details have been shown and described for accomplishing probably the best results, numerous changes may be made within the scope of the invention as claimed without sacrificing the main advantages thereof.

I claim 1. An elevator comprising a pipe, wheels disposed one at each end thereof, an endless belt trained around said wheels and having one of its reaches passing through said pipe, spaced disks secured transversely on said belt and having radial slots topermit them to pass around the wheels, an internal fiange extending longitudinally of the pipe and adapted to fill said slots as the disks pass upwardly through said pipe, and a track extending longitudinally of said pipe on the exterior thereof for reception in said slots as the disks travel downwardly, whereby to prevent vibration of the upper reach of the belt and to guide the disks on to the lower wheel.

2. An elevator comprising a pipe formed of a single sheet of metal with its edges brought together and extended outwardly to provide spaced parallel flanges, a board eX- tending longitudinally of the pipe and se cured at its longitudinal center to said flanges, upper andlower wheels at the upper and lower ends of said board, an endless belt trained around said wheels and having its lower reach disposed in the pipe adjacent the lower edge of said board, the upper reach of said belt extending along the upper edge of said board, and a plurality of disks secured transversely on said belt, said disks having radial slots to permit traveling thereof around the aforesaid wheels, said slots of upwardly moving disks being filled by the lower half of the board to prevent leakage while the slots of the downwardly moving` disks straddle the upper portion of said board whereby they are guided on to the lower wheel and whereby vibration of the upper reach of the belt is prevented.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
